Sokoban YASC 1.674 has been published

Brian Damgaard has published a new version of his great and widely used Sokoban YASC program.

The release notes for this new version:

• Reverse game play
  While playing the game in reverse mode, there was a special case where the program correctly prevented pulls that would lead to a deadlock, but it didn't provide a message explaining this.
  Thanks to Matthias Meger for reporting this omission.
• Scripting language
  Various improvements and bug fixes of the built-in SokLisp scripting language.
• Minor changes
